IP SLB stumping

I'm stumped on IP SLB.

On routers R1 to R3 I have configured a loopback0 ip 172.16.0.254/32 on each of them.

This is the config on my Router called R4.

ip slb serverfarm MYFARM
real 172.16.0.1
inservice
real 172.16.0.2
inservice
real 172.16.0.3
inservice
!
ip slb vserver VIRTUAL_SERVER
virtual 172.16.0.254 tcp www
serverfarm MYFARM
inservice

I used telnet 172.16.0.254 80 cmd on the hosts (R5,R6 and R7) pretty much at the same time but they seem to be all connecting to the 172.16.0.2 address. Shouldnt they be load balancing equally? it is set to default round robin

    No worries, i;ve figured it out and some.
    Also setup two different server farms and load balanced between them with 2 web servers per farm. Each farm served a different subnet.

    It's an amazing feature and I think often forgotten about.

    What did you figure out? Did it have to do with the load-balancing algorithm of WRR?
